1. A client with asthma develops respiratory acidosis. Based on this diagnosis, what should the nurse expect the client's serum potassium level to be?

• A. normal
• B. elevated
• C. low
• D. unrelated to the pH

Correct answer: B

Rationale: In respiratory acidosis, the body retains CO2, leading to increased hydrogen ion concentration and a drop in blood pH. As pH decreases, serum potassium levels increase due to the movement of potassium out of cells to compensate for the acidosis. Elevated serum potassium levels are expected in respiratory acidosis. Choice A ('normal') is incorrect because potassium levels are expected to be elevated in respiratory acidosis. Choice C ('low') is incorrect as potassium levels rise in this condition. Choice D ('unrelated to the pH') is incorrect as serum potassium levels are directly impacted by changes in pH in respiratory acidosis.

2. A client goes to the Emergency Department with acute respiratory distress and the following arterial blood gases (ABGs): pH 7.35, PCO2 40 mmHg, PO2 63 mmHg, HCO3 23, and oxygenation saturation (SaO2) 93%. Which of the following represents the best analysis of the etiology of these ABGs?

• A. tuberculosis (TB)
• B. pneumonia
• C. pleural effusion
• D. hypoxia

Correct answer: D

Rationale: A combined low PO2 and low SaO2 indicate hypoxia. The pH, PCO2, and HCO3 are normal. ABGs are not necessarily altered in TB or pleural effusion. In pneumonia, the PO2 and PCO2 might be low due to hypoxia stimulating hyperventilation, but the given ABG values specifically point to hypoxia as the primary issue.

3. For which adverse effect of the block does the postpartum nurse monitor the woman after receiving a subarachnoid (spinal) block for a cesarean delivery?

• A. Headache
• B. Pruritus
• C. Vomiting
• D. Hypertension

Correct answer: A

Rationale: The correct answer is 'Headache.' Postdural headache is a common adverse effect associated with a subarachnoid block due to cerebrospinal fluid leakage at the site of dural puncture. This headache worsens when the woman is upright and may improve when she lies flat. To manage this headache, bed rest and adequate hydration are recommended. Pruritus, vomiting, and hypertension are not typically associated with subarachnoid blocks. Pruritus, nausea, and vomiting are more commonly linked to the use of intrathecal opioids.

4. The client is preparing to undergo a total hysterectomy for advanced cervical cancer. The client is crying and says that she wants to have more children and is unsure if she should have the procedure. What should the nurse do?

• A. Allow the client to honestly discuss her fears and encourage her to talk more with her physician.
• B. Tell her the good things that she will be able to do without more children and encourage her to make a list of positive things.
• C. Explain to the client that her ovaries can be frozen for egg harvesting at a later time and she can find a surrogate.
• D. Advise the client to put off having the surgery until she is sure that she wants to undergo the procedure and notify the surgeon of the decision.

Correct answer: A

Rationale: In this situation, the most appropriate action for the nurse is to allow the client to express her fears and concerns openly. By encouraging her to talk more with her physician, the nurse is promoting effective communication and ensuring that the client receives adequate information to make an informed decision. Option A is correct because it acknowledges the client's emotions and empowers her to seek clarification and support from her healthcare provider. Options B and C do not address the client's emotional needs or provide a solution to her concerns regarding fertility. Option D is not appropriate as it does not prioritize the client's emotional well-being and delays necessary medical treatment for advanced cervical cancer.

5. Which behavior by a new nurse would indicate to the charge nurse that this nurse is following standard precautions?

• A. Wearing clean gloves while performing a heel stick on an infant
• B. Wearing the same gloves for assessments of clients in the same room
• C. Wearing sterile gloves when changing the urine bag and nasogastric canister of an infected client
• D. Donning a gown when responding to a request by the family to check the IV pump on a client with rotavirus

Correct answer: A

Rationale: The correct answer is wearing clean gloves while performing a heel stick on an infant. Standard precautions require the use of gloves when there is a risk of exposure to blood or body fluids. Clean gloves are suitable for this task as they provide adequate protection without being sterile. Choice B is incorrect because wearing the same gloves for different clients can lead to cross-contamination, violating standard precautions. Choice C is incorrect as sterile gloves are usually not required for changing a urine bag and nasogastric canister unless a specific aseptic technique is indicated; standard precautions do not demand sterile gloves for such tasks. Choice D is incorrect as donning a gown is not necessary for checking an IV pump unless there is a risk of exposure to bodily fluids that would necessitate full-body protection, which is not indicated in this scenario.
